AI GLOSSARY
MLOps
MLOps applies DevOps practices to machine learning. The goal: to deploy AI models into production in a reliable, repeatable, and scalable manner. Without MLOps, data science projects remain stuck in notebooks. With MLOps, they become reliable business tools.

Why MLOps Is Key to Success
Many AI projects fail not because of the model, but because of operations. MLOps bridges the gap between data science and production. Without MLOps, every ML project remains a one-off—with MLOps, AI becomes a maintainable, scalable system.
Reproducibility
Every result can be reproduced exactly—which is critical for debugging and audits.
Faster Time to Production
Automated pipelines get models live in days instead of months.
Fewer Errors
Manual deployments are sources of errors—MLOps automates and tests.
Scalability
MLOps grows with your portfolio—from your first model to dozens.
Compliance Capability
Audit trails, model maps, retraining history — evidence for the AI Act.
Collaboration
Data scientists, engineers, and operations staff work together in a structured manner.
What is MLOps?
MLOps (Machine Learning Operations) is the discipline that applies DevOps practices to machine learning projects. It encompasses processes, tools, and culture to reliably develop, deploy, and operate ML models.
Key areas: data management (versioning, quality, feature store), model development (experiments, tracking, reproducibility), deployment (CI/CD, A/B testing, rollbacks), monitoring (performance, drift, fairness), retraining (automated updates to new data).
Difference from DevOps: In addition to code, MLOps must also version, test, and deploy data and models. Model quality can degrade during operation (drift)—retraining and monitoring are key considerations. Additionally: fairness, explainability, and compliance.
For small and medium-sized businesses, MLOps represents the leap from a makeshift solution to standard operations. Without MLOps, every ML project remains a one-off solution. With MLOps, AI becomes a maintainable product—and the investment pays off even after the first model.
MLOps Techniques in Detail
These eight techniques form the backbone of professional MLOps setups:
Experiment Tracking
Model Registry
Feature Store
Automated Pipelines
CI/CD for ML
A/B Testing
Model Monitoring
Automatic Retraining
Best Practices for MLOps
These six principles have proven effective:
- Start small: Don’t try to do everything at once—increase maturity level by level.
- Version everything: code, data, models, configuration—ensure reproducibility.
- Test like software: Unit tests, integration tests, model tests—all automated.
- Monitor from the start: Don’t add monitoring later—monitor models and operations.
- Work cross-functionally: Data scientists, engineers, ops, and business users working together.
- Iterative improvement: Start with the basics, then automation, then advanced features.
Level 0
Manual
Manual work from the notebook to deployment. Initial pilot projects are often sufficient.
Manual
Level 1
Automated Training
Pipelines for training and deployment. Retraining as needed.
Automated
Level 2
Fully Automated
Automatic monitoring, trigger-based retraining, CI/CD. Mature MLOps.

Common Mistakes in MLOps
We often see these pitfalls:
- Too Many Tools Too Soon: Introducing all the tools at once — overwhelming the team.
- Data Science in a Silo: MLOps is just an IT thing—data scientists work in isolation.
- Notebooks in Production: Using Jupyter in production—not maintainable, not scalable.
- No feature store: Features are calculated differently in training and production—model quality suffers.
- Lack of monitoring: The model is running, but no one notices drift—until customers complain.
MLOps vs. DevOps vs. AIOps
A comparison of three related disciplines:
- DevOps: For traditional software — continuous integration, delivery, and deployment.
- MLOps: Extends DevOps to include data, models, drift, retraining, and fairness.
- AIOps: AI for IT operations — anomaly detection, root cause analysis, auto-remediation.

Frequently Asked Questions About MLOps
-
When do I need MLOps?
As soon as an ML model is running in production on a long-term basis or needs to be retrained. MLOps becomes essential once you have two or more models in production.
-
What tools are included as standard?
MLflow (experiment tracking), DVC (data versioning), Airflow or Kubeflow (pipelines), Feast (feature store), Evidently (monitoring).
-
Cloud or on-premises?
The cloud enables a quick start (AWS SageMaker, Azure ML, GCP Vertex). On-premises solutions are used for sensitive data or compliance requirements. A hybrid approach is often the reality.
-
How much does it cost to set up MLOps?
Starting point: 50,000–150,000 EUR. Fully developed platform: 200,000–500,000 EUR. ROI is typically achieved starting with the third model in the portfolio.
-
What's the difference between this and DevOps?
MLOps must also version data and models, monitor model drift, automate retraining, and ensure fairness.
-
Who should be part of the MLOps team?
At least one ML engineer with a focus on MLOps. Ideally: data scientists with a basic understanding of MLOps, and a dedicated platform team for 3 or more models.
-
How is MLOps related to the AI pipeline?
AI pipelines are a building block of MLOps. MLOps is the broader discipline—pipelines, culture, governance, and tools.
